Nanometer material repairing agent capable of repairing engine cylinder block

Abstract

The invention discloses a nanometer material repairing agent capable of repairing an engine cylinder block. The nanometer material repairing agent comprises the components in percentage by weight as follows: 2-15% of nano-copper, 1-5% of nano-LaF, 2-5% of MoS2 dispersion liquid, 0.5-1% of dispersant, 2-15% of viscosity index adjustor, and 66-92% of synthetic lubricating oil. The nano-copper used is prepared by a liquid phase method. The nanometer material repairing agent disclosed by the invention can automatically repair the surface of the worn engine cylinder block, so that the pressure of the cylinder is improved, the resisted oxygen capability of engine oil is improved, and the power of the engine is enhanced.

Description

technical field [0001] The invention relates to a nanomaterial repairing agent, which is used for repairing an engine cylinder block and belongs to the field of material chemistry. Background technique [0002] After a long-term driving of the car, the piston of the engine cylinder will wear due to frequent movement, resulting in an increase in the gap between the piston and the cylinder wall, resulting in a decrease in the power of the car, burning oil and smoke. For the above problems, the engine is usually used. A powerful fixer to fix it. [0003] The commonly used strong repair agent for automobile engines is generally made of dialkyl thiophosphate ZDDP. Due to the high content of phosphorus in ZDDP, which exceeds the national standard, this product is usually only used for low-end cars, and as people pay more attention to environmental protection. As the requirements increase, this product is facing a situation of elimination; at the same time, the phosphorus content ...

AI Technical Summary

Problems solved by technology

[0003] Commonly used strong repair agents for automobile engines are generally made of dialkylthiophosphate ZDDP. Due to the high phosphorus content in ZDDP, which exceeds the national standard, this product can only be used for low-end cars, and with people's environmental protection With the increase of requirements, this product is facing elimination; at the same time, the phosphorus content of ZDDP will seriously hinder the exhaust gas purification effect of the three-way catalytic converter, and in some cases, it will also lead to the failure of the oxygen sensor for monitoring the air-fuel ratio.

[0004] Most common lubricating oil products have the following problems: (1) In pure oil medium, the friction coefficient is greater than 0.003, and will lose the proper lubricating function under dry friction conditions; (2) The lubricating effect still cannot meet the increasing standards (3) In terms of anti-wear and anti-friction effects, it still cannot meet the use requirements under specific harsh conditions, such as long-term heavy-load operation, short-term use in the state of less oil or even no oil after oil leakage

[0005] In response to existing product defects, some engine repair agents made of nano-materials have also appeared on the market, but most of these materials face difficulties in the production process or dispersion process of nano-materials, the actual effect is not good, and the production and use costs are high.
